While doing this:
* Explicitly assign RPC program and version information in
_nfs_check_rpc_common(). This is more lines of code but is easier
to read.
* Don't print the options when starting a service. Trying to print it
makes the code messy for little benefit.
Update the eventscript unit testing code and a Ganesha test to
reflect this.

That is, /dev/null the "stop" output. This is consistent with the way
CTDB generally deals with the output when stopping a service.
It also makes updating the eventscript unit tests easier.

This avoids issuing multiple "ctdb killtcp" commands to terminate tcp
connections, one per connection. This will considerably reduce the
time when there is a large number of tcp connections. This also makes
it possible to avoid calling "ctdb killtcp" when there are no connections.
Add a couple of unit tests for killtcp and update eventscript unit
test infrastructure to support.

If some nfsd threads are still alive after a shutdown during a restart

60.nfs and 60.ganesha touch $statd_update_trigger every time they're
run. This stops the statd-callout updates from ever being called.
Make this logic self-contained and move it to new function
nfs_statd_update() in the functions file. Call this in 60.nfs and
60.ganesha with the appropriate update period as the only argument.

(This used to be ctdb commit d9775fcbd6e30eef8382bea68e2f9bad2309f2c1)
This is intended to replace nfs_check_rpc_service(), which builds
configuration into eventscripts.
nfs_check_rpc_services() uses a directory of configuration checks that
can be edited by an administrator. The files have one limit check and
a set of actions per line. The program name is extracted from the
file name.

This has 2 advantages:
1. It uses get_tcp_connections_for_ip() to check for leftover
connections, instead of custom code.
2. It checks for the timeout condition before sleeping. The current
code sleeps and then checks, so wastes a second.

Complicated argument handling was introduced to deal with multiple
services per eventscript. This was a failure and we split 50.samba.
This simplifies several functions to use global $service_name
unconditionally instead of having an optional argument.
$service_name is no automatically longer set in the functions file.
This means it needs to be explicitly set in 13.per_ip_routing because
this script uses ctdb_service_check_reconfigure().
Eventscript unit test infrastructure needs to set $service_name during
fake service setup, and policy routing tests need to be updated
accordingly.

The current logic is horrible and creates an unnecessary file. Let's
make the script debug level independent of ctddb's debug level.
* Have debug() use $CTDB_SCRIPT_DEBUGLEVEL directly
* Remove ctdb_set_current_debuglevel()
* Remove the "getdebug" command from ctdb stub in eventscript unit
tests
* Update relevant eventscript unit tests to use
$CTDB_SCRIPT_DEBUGLEVEL
